Kantou, Pandemonium—Once known as Kajou City, a central metropolis of the Kantou region.A few years ago, it was connected to the "Abyss," an alternate dimension where primal magic energy swirls, turning the place into a demonic city full of supernatural phenomena.
Upon the emergence of unidentifiable immortal "Witches," the government quarantined the metropolitan area and erased it from the national map, leaving it to ruin.
